大型项目linux自动化版本发布脚本（shell）之tomcat、nginx服务脚本
最近，又临近博主所负责的一个大型项目的发版了。之前有提到过，该项目涉及到30-40台服务器的发版。且项目客户规定发版需在晚上10-11点左右开始进行，这里博主不得不说每次发布最后都是眼花缭乱。
博主最近想了下，还是决定做些自动化发版的脚本；首先，在批量关闭服务器、批量重启服务器、批量延迟重启服务器、以及批量nginx重启、kill、reload方面都可以做成自动化脚本。当然，还有资源备份、代码备份等等。
自动化脚本来发版后，将一键关闭、重启所有tomcat，一键实现所有Nginx的downline、online、kill，一键备份代码（包括定时任务代码、普通服务器代码、接口服务器代码、消息服务器代码等），一键资源备份，一键数据库备份。当然，在执行自动化脚本之前，服务器必须先配置ssh免密登录。
通过上面的自动化脚本后，我们的整个发版过程就非常简单了：
（1）通过增量打包工具patch-generator-desk实现本次版本增量代码打包，具体参照patch-generator-desk打包软件
（2）使用xftp上传覆盖代码，由于打包出来是可以直接上传实现替换，故此步骤非常简单
（3）一键执行代码备份脚本
（4）执行n_downline_ssh.sh脚本实现Nginx请求重写跳转
（5）执行一键关闭所有tomcat服务器脚本t_kill.sh
（6）执行资源文件以及数据库脚本一键备份的脚本
（7）执行一键启动所有tomcat服务器脚本t_start.sh/t_restart_delay.sh
（8）执行n_go_online_ssh.sh脚本实现Nginx重写加载非跳转配置实现上线
（9）校验本次发版内容完整性
（10）发版结束........
以下是自动化脚本内容：

最后总结，由于博主其它数据资源备份脚本还没写好，今天先写到这里，其它脚本后续将补充到此篇文章。以上是博主本次文章的全部内容，如果大家觉得博主的文章还不错，请点赞；如果您对博主其它服务器技术或者博主本人感兴趣，请关注博主博客，并且欢迎随时跟博主沟通交流。
